血清前白蛋白与肝细胞癌患者肝切除术预后的相关性研究

Serum prealbumin predicts prognosis of hepatectomy in patients with hepatocellular carcinoma

目的研究肝切除术前血清前白蛋白水平与原发性肝细胞癌(HCC)患者肝切除术预后的相关性。方法回顾性分析2007年8月到2016年10月在广西医科大学附属肿瘤医院接受肝切除术治疗的HCC患者临床资料。分别以前白蛋白200 mg/L和采用最大选择秩统计量法预测的前白蛋白为界值进行分组,并分别分析术前血清前白蛋白水平与临床病理特征的相关性。采用Kaplan-Meier法计算不同界值水平患者的累积生存率;采用C。x比例回归模型分析血清前白蛋白与HCC患者肝切除术预后的关系并进行校正;以肝硬化、甲胎蛋白水平及巴塞罗那临床肝癌分期为分层变量进行分层分析并分析其与血清前白蛋白的交互作用。结果共纳入2022例患者,其中男性1739例,女性283例,年龄(49.5±11.2)岁冲位随访37.4个月。最大选择秩统计量法预测的前白蛋白最佳界值为166 mg/L。无论以前白蛋白200 mg/L或前白蛋白166 mg/L为界值,多因素分析显示术前血清前白蛋白水平是患者预后独立的危险因素(P<0.05)。术前血清前白蛋白>200 mg/L(>166 mg/L)患者的预后显著优于前白蛋白≤200 mg/L(≤166 mg/L)的患者,差异均具有统计学意义(均P<0-05)。调整混杂因素后,结果表明前白蛋白水平与HCC患者预后有关联[界值200 mg/L:HR(95%CI)为1.59(1.35〜1.86),界值166 mg/L:HR(95%CZ)为1.69(1.44^1.98),均P<0.05]。分层分析结果表明前白蛋白水平与HCC患者预后的关系较为稳健。结论术前血清前白蛋白是HCC患者预后独立危险因素,对HCC患者的预后有一定预测价值。

Objective To study the correlation between serum prealbumin level before liver resection and prognosis of patients with primary hepatocellular carcinoma(HCC).Methods The clinical data of patients with HCC who underwent liver resection at the Affiliated Tumor Hospital o£Guangxi Medical University from August 2007 to October 2016 were retrospectively analyzed.The previous albumin of 200 mg/L and the pre-albumin as predicted by the maximum selection rank statistic method were used as the bounding group,and reduced groups and the correlation between pre-operative serum pre-albumin levels and clinicopathologi-cal characteristics were analyzed.The Kaplan-Meier method was used to calculate the overall survival rate of patients with the different cutoff levels.The Cox proportional regression model was used to analyze,and cirrhosis,alpha-fetoprotein levels and Barcelona Clinic Liver Cancer staging were used to adjust the relationship between serum prealbumin and prognosis of liver resection for HCC patients.Analysis of stratified variables was performed and their interactions with serum prealbumin were analyzed.Results Of the 2022 patients included in this study,there were 1739 males and 283 females.Their age was 49.5±11.2 years.The median follow-up was 37.4 months.The optimal cutoff value of prealbumin predicted by the maximum selection rank statistic method was 166 mg/L.Regardless of the cutoff values of previous albumin 200 mg/L or prealbumin 166 mg/L,multivariate analysis showed that preoperative serum prealbumin level was an inde pendent prognostic risk factor for patients(P<0.05).The prognosis of patients with>200 mg/L(>166 mg/L)serum prealbumin before surgery was significantly better than that of patients with W200 mg/L(W 166 mg/L)prealbumin,the differences were significant(all P<0.05).After adjusting for confounding fac­tors,the prealbumin level correlated with prognosis of patients with HCC[cutoff value 200 mg/L:HR(95%CI)was 1.59(1.35-1.86),cutoff value 166 mg/L:HR(95%CI)was 1.69(1.44-1.98),all P<0.05].The results of stratified analysis showed that the relationship between prealbumin levels and the prognosis of HCC patients became more robust.Conclusions Preoperative serum prealbumin was an independent risk factor for prognosis of HCC patients,and it had predictive value on prognosis of HCC patients.
